Louisiana Truck Mud Flap Law
Louisiana keeps it broad. Every motor vehicle except motorcycles must run fenders, covers, flaps, splash aprons or fender flares at least as wide as the tires (RS 32:364). Trailers and towed units in a combination need adequate splash guards too (RS 32:384). No inch-clearance is set, so State Police judge whether spray is controlled. Ag and forestry haulers, sub-1,500-pound rigs, and vehicles never built with the gear are exempt. Expect a correctable equipment ticket, not an out-of-service.
A detail here is flagged medium confidence — confirm with the state statute before you rely on it.
